Downpour expected in time for Tuesday evening commute in Marin County

Driving rain slowed the early-morning commute Tuesday, and forecasters said a heavier downpour is due just in time for the return home this evening.

"This is nothing. What we're seeing now is just this is just heavy drizzle," National Weather Service forecaster Steve Anderson said of rain pelting the North Bay at 6:45 a.m. "The evening commute will be slow because the rain will be heavier."

Bursts of rain curbed visibility and slowed traffic. No major accidents were reported by 7 a.m. in Marin County.

Anderson said a massive Gulf of Alaska storm extending from Canada to Northern California will dump 1.5 inches of rain on the North Bay before a cold front moves in Wednesday morning.

The good news: Thanksgiving will be dry "for sure," Anderson said, with temperatures in the 60s. "It will be sunny." The weekend looks good, too, he said.

The storm that moved in to Marin early Tuesday is the edge of "one big system rotating down," he said, adding the really heavy downpour is expected to sweep in between 4 p.m. and 10 p.m. Tuesday.
